Warehouse EV charging: using SECR data to plan electricity procurement

Warehouse EV charging: using SECR data to plan electricity procurement

Electrifying a warehouse fleet affects more than transport emissions. It can change electricity demand, site load profiles, contract requirements and future budgets. A successful warehouse EV charging project therefore needs to connect infrastructure planning with the way your organisation buys and manages energy.

Streamlined Energy and Carbon Reporting (SECR) requires qualifying organisations to bring together information on electricity, gas, transport fuel and associated emissions. Our SECR service supports data collation and validation, emissions calculations and compliant disclosures.

Used carefully, the same dataset can provide an initial evidence base for estimating where fleet electrification may shift energy consumption from transport fuel to electricity. It should inform, rather than replace, a site feasibility study and detailed charging-demand assessment.

Planning a fleet transition or approaching an energy contract renewal? Speak to Zenergi about bringing SECR insight, EV charging feasibility and energy procurement into one coordinated plan.

Why SECR matters for warehouse EV charging

SECR aims to improve transparency around energy use and greenhouse gas emissions. Qualifying organisations must report relevant electricity, gas and transport fuel consumption, including fuel used in company-operated or grey fleet vehicles. Zenergi helps organisations understand where they use the most energy, manage reporting across Scopes 1, 2 and 3, and identify opportunities to reduce consumption, costs and emissions.

For a warehouse or distribution operation, the transport element creates a documented baseline for part of the fleet’s current energy use. By combining that baseline with operational data, an organisation can start to estimate how vehicle electrification could affect future electricity volumes. This creates a clearer connection between compliance reporting, capital planning and the next procurement cycle.

What SECR data can contribute to charging-demand planning

Establish the fleet energy baseline: SECR data can show reported transport fuel consumption and associated emissions for the reporting period. This helps clarify the scale of current fuel use within the relevant organisational boundary.

Fuel data alone cannot determine the number or capacity of chargers required. For planning warehouse EV charging, assess it alongside vehicle numbers, fleet replacement plans, journeys, dwell times, depot schedules and the proportion of vehicles expected to charge at each location.

Review existing electricity consumption: A warehouse should understand its current electricity use before adding a material new load.

Our Metering and Data Services provide a transparent, real-time view of energy consumption, while our procurement service uses consumption information to assess contract options.

Reviewing detailed consumption patterns can help identify when warehouse demand is already highest, whether charging may overlap with those periods and which assumptions need testing during feasibility.

Check data quality and boundaries: Our SECR support includes data collation, validation, emissions calculations, quality assurance and compliance checks.

A forecast based on incomplete fleet or site information can create a misleading procurement requirement. Before using SECR information for investment planning, confirm that the reporting boundary reflects the vehicles, warehouses and electricity supplies involved. Record any gaps and use scenario ranges where future fleet plans remain uncertain.

How to forecast electricity demand for warehouse EV charging

1. Define who will use the chargers: Our EV charging solutions can support employees, clients and on-site visitors. A warehouse project may also need to serve operational fleet vehicles. Separate these user groups because their charging windows, access requirements and commercial purpose may differ. Decide whether the priority is fleet availability, workplace charging, visitor convenience or a combination of uses.

2. Test site suitability: Our EV charging service assesses site suitability, specific requirements and potential challenges. Our feasibility report can set out a proposed solution strategy, estimated budget costs and recommended next steps.

3. Build more than one demand scenario: Create a base case, a phased-growth case and a higher-demand case. For each, estimate the vehicles charging at the warehouse, their energy requirement, expected connection times and implementation date. Then combine the additional volume with existing site consumption.

4. Align the forecast with contract timing: Zenergi assesses suppliers, contract durations and purchasing options against consumption, budget requirements, risk appetite, market conditions and sustainability objectives. We can compare fixed, flexible and green energy options and provide clear comparisons and risk assessments.

Planning warehouse EV charging ahead of renewal allows forecast demand to be considered when the next electricity contract is evaluated, rather than after the purchasing decision.

How to approach an EV charging tariff comparison

An effective EV charging tariff comparison should consider overall electricity requirements and operating priorities, not a headline rate in isolation.

Our procurement approach considers price alongside contract terms, cost visibility, supplier suitability, governance, compliance and ongoing support.

When comparing electric vehicle charging tariffs , consider:

  • how well each option reflects forecast consumption
  • whether fixed, flexible or green purchasing fits your budget and risk appetite
  • the contract length and how it aligns with the rollout
  • the comparability of supplier terms
  • the level of cost visibility and support available

Zenergi can prepare like-for-like commercial energy quote comparisons and explain the trade-offs. Fixed contracts generally provide greater price certainty for an agreed period, while flexible purchasing spreads decisions across different market points and carries a different form of market exposure.

EV charging prices may refer either to electricity supply costs or to the amount employees, visitors or other users pay to access the infrastructure. Keep these decisions separate: the supply contract affects the cost of electricity entering the site, while any user-charging model forms part of the wider commercial strategy.

A robust review of electric vehicle charging tariffs should use a tested demand range and consistent contract scope. Headline EV charging prices are only meaningful when consumption assumptions, contract periods and service terms are comparable.

A coordinated route from compliance to delivery

A practical sequence for warehouse EV charging is:

  1. Validate the baseline. Complete SECR data collation and quality checks, then identify the relevant fleet and electricity information.
  2. Assess feasibility. Confirm site suitability, project requirements, challenges, budget expectations and next steps.
  3. Model demand before procurement. Add tested charging scenarios to existing electricity requirements and review contract timing.
  4. Compare purchasing options. Complete the EV charging tariff comparison using like-for-like supplier and contract information.
  5. Tender and deliver. Zenergi can prepare technical specifications and drawings, issue tender documents, analyse contractor pricing, support contractor selection and project-manage implementation.
  6. Inspect and monitor. Zenergi can inspect the installation at handover and confirm relevant testing and commissioning certificates. Ongoing consumption data can then support energy management and future reporting.

This sequence reduces the risk of separate teams working from different fleet, energy and budget assumptions. It also creates an evidence trail from annual disclosure through to investment and contract decisions.

How Zenergi can support your project

Zenergi brings together services across compliance, procurement and project delivery:

  • SECR support: data collation and validation, emissions calculations, compliant disclosures, quality assurance and energy-efficiency opportunities
  • EV charging solutions: feasibility, strategy, budget estimates, technical specification, tendering, project management and post-installation inspection
  • Energy procurement: supplier and contract comparison informed by consumption, budget, risk appetite and sustainability objectives
  • Metering and Data Services: visibility of consumption to support monitoring and decisions

Our Links Academy case study demonstrates EV charging delivery across three sites as part of a wider solar PV and sustainability project. Although a warehouse will have different requirements, the case study provides relevant evidence of our ability to coordinate multi-site EV infrastructure delivery.

Frequently asked questions

No. SECR supplies a useful energy and emissions baseline, but a full forecast also needs operational fleet assumptions and site feasibility work.Treat the data as one input to the business case, not as a substitute for technical assessment.

Begin before the next procurement decision wherever possible. This allows the buying strategy to reflect tested charging scenarios, contract start dates and phased implementation.

Compare like for like. Clarify whether the figure concerns the site’s electricity supply or charges applied to infrastructure users, then review consumption assumptions, contract terms, supplier conditions and service support.

Yes. Zenergi offers SECR reporting support, integrated EV charging services and energy procurement. This allows your organisation to draw on connected expertise while retaining clear decisions at each stage.
